Why Do Whales Breach?

Ever wondered why sperm whales breach? This is a question we get asked often by our visitors, so I have put together what is hopefully some helpful information to this interesting question. While our visitors might think the whales are doing this to make for that Kodak moment it is likely they are breaching for other purposes.

Likely theorises for breaching include competitive displays between males (we only have the male sperm whales off the Kaikoura Coastline), it could be a warning of danger coming such as predators in the area. Another theory is that it could be some form of communication – sound travels faster in water than air and it could be a quick way to transmit information to other whales in the area. It has also been suggested that it might be a technique to stun or scare their prey which in turn helps them feed as well as shed loose skin which may be irritating them.

There have been times out on our tours when we have seen first-hand these theories put into practise. I recall one day seeing a sperm whale named Droopy Flukes breach beside our vessel around 20 times, during this amazing display we noticed that he shed a layer of skin going from a dark brown colour to a much lighter shade of brown. While it was a spectacular sight to see I am sure it was also a great feeling for the whale to be rid of that itchy shedding skin. 

Sperm whales are known to eat a lot of squid, squid has beaks which are hard to digest and often end up causing constipation for the whales. We have seen sperm whales breach to relieve them-selves of this discomfort leaving behind evidence of this on the surface... As you can imagine the force and pressure of an 18-20m / 45-55 tonne whale propelling itself out of the water is indeed spectacular and would help relieve this irritation.

More recently we have had a couple of humpback whales spend some time in Kaikoura, during their time here they have also been observed breaching rather regularly much to the delight of the passengers and crew alike. Theories around humpback whales breaching are much the same to the sperm whales however with the humpback whales they too maybe trying to get rid of parasites built up on their sensitive skin.

One of the humpback whales that recently visited with us actually had some fishing net caught around it’s long pectoral fin which seemed to have been there for quite some time, this was obviously causing the young whale some distress but eventually after a lot of breaching and slapping of its fin on the water it was able to free itself of this netting.

It really is a blessing to be able to view these beautiful creatures in their natural environment. We never know what to expect from one day to the next when out whale watching so as you can imagine when we do get to see a sperm whale breach (or a humpback whale for that matter) even the crew get very excited to see something so amazing take place. I know some of my fondest memories of my time out on the sea are of those moments when the whales would do something out of the ordinary and take you by complete surprise and leave you with a precious memory of nature at its best.

Over the last week we had fantastic tours with great sightings of semi-resident sperm whales Tutu, Tiaki and Manu who were feeding reasonably close inshore. When time allowed we also viewed dusky & Hector’s dolphins, NZ fur seals and marine birds.

Winter has been making itself well and truly known over the last few days which reminds us to be taking care on the roads especially earlier in the day when ice can be an issue. For those of you who enjoy time on the slopes, local family owned ski field Mt Lyford is due to open on the 29th June (just in time for the school holidays!).

REMINDER - REGULAR, SCHEDULED CLOSURES OF STATE HIGHWAY 1 SOUTH OF KAIKOURA

• The highway will be open during daylight hours on Fridays, Saturdays, Sundays and Mondays (perfect for a long weekend getaway)

• The highway will be closed on Tuesdays, Wednesdays and Thursdays for repairs to take place. 

• The closure schedule is expected to remain in place until the end of September.

There is a possibility of short delays and it will be 30km/hour through parts of the route. Inland Route 70 remains open 24 hours a day 7 days a week.

As we enter into the cooler winter months it is a good reminder to take extra care on the roads and to check the NZTA website for road updates before traveling.

Progress is being made on the repair of the Kaikōura Marina and we continue to switch between using a berth and our modified trailer unit for launching our vessel Tohorā, when and where possible we are also making use of the public jetty that we have modified, this is due to tidal restrictions and repair work as a result of the coastline lifting by +1.0m. It is anticipated that the Kaikōura Marina will be fully restored in October 2017.

Currently our available tour times are based around the tide times on the day and may differ from the tour times originally advertised, please bear with us as we continue to work toward being fully operational again.
